Background
The method is characterized in that backfill compaction is needed to be carried out on a foundation in the building construction process, in order to ensure the quality of the backfill compaction, a backfill compaction detector is needed to be used for detection, a front end probe rod of the compaction detector is well connected with a measuring contact rod head during detection, applied pressure is vertically inserted into a soil layer of a measured point, the depth is 0-10-30 cm, a dynamic measured value is displayed on an instrument screen in real time in the whole penetration process, the density in the whole process of drilling depth and the whole process of the change of the weak strength of a soil layer can be observed through the change of the dynamic value, meanwhile, an auxiliary mechanism is needed to be used for guiding stability in order to ensure the stability of vertical insertion, but the measuring contact rod head is easy to rub and collide with a guide sleeve of the auxiliary mechanism when inserted into the guide sleeve of the auxiliary mechanism, the measuring contact rod head is damaged, and the accuracy of the whole detection is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem of the existence, the utility model provides a closely knit degree detection device of backfill soil.
The utility model discloses a realize through following technical scheme:
the utility model provides a closely knit degree detection device of backfill, includes closely knit degree detector and complementary unit thereof, and this complementary unit includes the fixed leg that bottom plate and lower part set up, and bottom plate upper portion is through frame and the uide bushing outer wall fixed connection of setting at central authorities, the uide bushing bottom extends to the bottom plate lower part, the inside annular of uide bushing is evenly opened there is a plurality of circular recess, be provided with the rotator in the circular recess, the rotator comprises the rubber layer of steel ball and outside setting.
The outer side of the rotating body extends out of the outer side of the circular groove by 1mm-2 mm.
The inner diameter of the guide sleeve is matched with a measuring contact rod head arranged on the lower portion of the compactness detector.
Compared with the prior art, the beneficial effects of the utility model are that: this practicality is through setting up rolling rotator in closely knit degree detector complementary unit's uide bushing, can guarantee the smooth and easy stability that moves down and can prevent to measure the contact bar head friction damage again when measuring the contact bar head atress and move down, sets up the rubber layer in the steel ball outside of rotator moreover, plays to measuring the extruded cushioning effect of contact bar head, plays the buffering guard action to measuring the contact bar head, wholly guarantees the accuracy nature of measuring the contact bar head test data.
